May 20, 2017 - The river of stars, the Milky Way, arching over the scenic bend of the Red Deer River, Alberta, Canada, from the Orkney Viewpoint overlooking the Badlands and river valley, in a 270 degree panorama. To the north at left, a weak aurora shines along the horizon. Bands of airglow also colour the sky to the east at centre, and perpetual twilight lights the sky at far left. To the south at right, the Milky Way becomes lost amid the light pollution from Drumheller, Alberta, made more obvious by some clouds drifting through. So this is a study in skyglows: aurora, twilight, airglow, Milky Way and urban skyglow, and of the contrast between the natural sky and light polluted sky. The most prominent stars reflected in the still waters of the river are the stars of Delphinus the Dolphin.
